correct, but it is not our intention to produce data that is better suited for
kamikaze drivers than normal users.. is it?

Imho conditional restrictions have everything we need, it provides perhaps a little
bit more than that and we should pick one preferred method.

- mentions lanes and directional restrictions explicitly

so perhaps
lanes:forward:conditional=2 @ (09:00-17:00)
lanes:backward:conditional=2 @ (17:01-8:59)

I suspect there might be some places already tagged somehow similar like this 
but can't find them now..

As it has not been implemented in any routers that I know about it might be
good to ask in the issue trackers of some routers if they have an idea what 
would be reasonably easy to implement.
